Apparently there is a scene in this... movie where the lead actress is in a mud fight type scenario, and according to interviews was actually involved with (as opposed to a stunt double).
Just wanted to mention here since I was just made aware through Amanda the Jedi's review on YouTube!
It's a male vs. female mud fight in the rain, almost all stunt doubles and then makeup mud in the next scene. Starts with a decent faceplant but otherwise disappointing.
